it's in every flight manual that I ever looked at...reduced power climbs use more fuel.
and in every Airplane Flight Manual that i have ever looked at, they dont show ANY DATA for ALL ENGINES! Therefore I dont see where you are getting your information from!
is just a tactic by your boss's to keep you from over temping, torqueing, over limiting your engines
Sorry but we have FADEC's! As i said to you before, go talk to your local RR/PW/GE rep and tell him that you are going to use their engines at full power, ask them how long will they guarantee the engine.
